SPECIFICATION forming part of Letters Patent No. 775,642, dated November 22, 1904.

Application filed April 4, 1904. Serial No. 201,537. (No model.)

To all w/wm it may concern:

Beit known that I, GEORGE SAMUEL BAKER, a subject of the King of England, residing at Willesden Junction,MiddleseX,England, have invented certain new and useful Improvements in Sandwich Biscuit Coating Machines, of which the following is a specification.

This invention relates to machines for coating biscuits with cream or the like and placing other biscuits on top to form a sandwichbiscuit, such as described in the specification of United States patent to Baker and Carr, N 0. 696,536, dated April 1, 1902; and the object is to square up or adjust the biscuits in proper relation to the table or web carrying them and to press such biscuits after they have passed from under the respective biscuit and cream hoppers.

To this end over the table or web of the machine I provide two devices operated from any desired moving part of said machine viz. first, an adjusting device comprising a series of resilient or resiliently-mounted plates,

which are caused to descend and move toward one another to square up the biscuits on all four sides, whereupon the biscuits are moved along on the web to the second device, comprising a presser-plate operated from the same source as the adjusting device, which firmly presses the biscuits one upon the other.

The improvements are represented in the accompanying drawings, wherein like letters of reference indicate corresponding parts throughout, and in which- Figure l is a side elevation, partly in section, of the biscuit-adjusting device. Fig. l is a detail view of part of Fig. 1. Fig. 2 is a cross-section thereof on the line 2 2 of Fig. 1 with certain parts omitted, and Fig. 3 a plan view. Fig. 4 is an end view, partly in section, showing the side adjusting-plates omitted from Fig. 2. Fig. 5 is a section on the line 5 5 of Fig. 4:. Fig. 6 is a plan view of the side adjusting-plates shown in Fig. 4. Fig. 7 is a side elevation, partly in section, of the pressing device and its operating mechanism; and Fig. 8 is a detail View of part of Fig. 7.

Referring to Figs. 1 to 3, a represents a bar adapted to be given a reciprocating movement by any moving partfor instance, the pusherplate of the machine. (Not shown.) When this bar is moved in the direction indicated by the arrow, the rows of biscuits are stationary. Upon said bar a isa cam or projection b, Fig. 1*, adapted to engage and move from right to left a trip-lever 0, mounted upon a shaft 0*, extending across the machine and provided at each end with a rigid arm 0, connected, by means of a link 0 to a vertical rod or spindle it, on which is mounted a large bracket d of the shape shown in Figs. 1 and 2. The bracket d rests on a shoulder al of said spindle it and is held down on the shoulder by a spring g bearing at one end on the top of the bracket and at the other end againsta collar 2', adjustably fixed upon said spindle. Brackets f, fixed to the machine-frame, act as guides for the brackets cl, which slide on them and at their upper ends are bent to form bearings for the ends of the spindles h. The brackets d are each provided with two recesses, in which blocks Z0 are adapted to slide, these blocks being operatively connected to the respective spindle h by means of a pair of bell-crank leversj on the other side of said blocks, pivoted at f to d, and integral with the blocks Zn or connected thereto are curved depending brackets m, from which rods carrying the end adjusting-platesl are suspended. A powerful spring 0 is provided, connected at one end to the machine-frame and at the other end to a pin 0 on an arm 0 rigidly mounted on the aforesaid cross-shaft 0 The action of this part of the device is as follows: On the bar a being moved in the direction of the arrow shown in Fig. l the cam b engages and rocks the trip lever c from right to left. This movement rocks the shaft 0*, and thus depresses the arms 0, links 0 and consequently the brackets 0Z, down onto the shoulders a, Fig. 1, of the fixed bracket f, thus bringing the plates Z onto the table of the machine. Then the arms 0 move down still farther, compress the spring 9 by meansof the spindles it and collars t' thereon, and move the long arms of the bell-crank levers j downward independently of the brackets d, which are now stationary. This movement of the bell-crank levers j forces the blocks Z simultaneously inward toward one another, and thus causes brackets m by means of the rods 11, on which the side adjusting-plates.

the sockets Z of the plates Z have limited sliding movement, each rod at having a collar n thereon, between which and the platela spring n is placed, as more particularly shown in Fig. 3. The rods n are also screw-threaded to engage in the brackets m and are provided with set-nuts 72 On release of the trip-lever c from the cam 72 the spring 0 returns all these parts to their original or uppermost position.

1 will now refer to Figs. i to 6, which show Integral with or connected to caps d, bolted to the brackets d, Fig. 2, are arms 05 which support bellcrank levers d, the longer arms of which are connected to the spindles h by means of links 01. The shorter arms of the levers 62* carry the pair of bars 19 and p, to which the respective sets of side adjusting-plates q and q are connected. The short arms of the levers d are connected, by means of pins 03 to the respective bar 0 or 10, each of these pins being connected to the bar which it is intended to operate, but engaging a slot p or p in the other bar. The plates (1 q are preferably made of thin resilient metal, so that they will give under excess pressure without breaking the biscuits. The action of the mechanism just described is as follows: When the movements previously described for operating the end adjusting-plates take placethat is to say, when the brackets d are depressedthe plates 9 and g'are brought down upon the table, and on further depression of the spindles k the bell-crank levers dare rocked by means of the links d connected to said spindles it, thus causing the bars p and p to be moved one in one direction and the other in the opposite direction toward opposite sides of the tables, respectively. This brings the plates q and q toward one another to adjust the biscuits m from the side simultaneously with the adjustment from the ends by the plates Z, as before described. The shape of the plates 9 q is preferably as shown in Fig. 5.

After being adjusted the biscuits are carried along on the table and pressed by a device represented in Figs. 7 and 8. This device comprises a bracket 8, fixed to the machine-frame and in which is adapted to slide a block 8, through which passes an adjustingscrew 8 i This screw 8 is provided at its lower end with a collar .9 and slidably carries the presser-plate 8*, extending across the machine, the plate being secured by a nut 8 against which it is held by a spring 8. Similar mechanism is arranged at the opposite side of the machine. When the lever 0, Fig. l, is tripped by the cam I), as described, and the shaft 0* rocked, arms 0 on the latter (one on each side of the mechanism) push rods 0 in the direction indicated by the arrow, and thus force back the longer arms 0 of hellcrank levers, the shorter arms 0 of which are connected to the slides s by pin-and-slot connections 0, thus causing said slides, and consequently the presser-plate s, to be pressed down upon the row of biscuits beneath said plate.

As before mentioned, when the trip-lever c is released from cam b all the parts are returned to their uppermost positions, thus allowing another row of biscuits to be moved along on the table to be adjusted and pressed.
